Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If unidirectional infrared communication devices are used for hydrogen fueling control, then the system structure is simple, but the communication reliability and safety are insufficient
Solution Approach 1:
The patent implements bidirectional communication between the vehicle terminal and dispenser terminal, enabling real-time feedback mechanisms. The vehicle terminal can send fueling requests and receive confirmation responses, while the dispenser terminal can send status updates and safety alerts back to the vehicle terminal, creating a closed-loop communication system that significantly improves reliability over unidirectional communication.
Solution Approach 2:
The system transitions from conventional unidirectional infrared communication to bidirectional communication protocols, discarding the limitations of the old system while recovering and utilizing modern communication capabilities for enhanced safety and reliability in hydrogen fueling operations.
2Productivity
If conventional hydrogen fueling protocols are used, then the system is easy to operate, but the fueling efficiency and speed are slow
Solution Approach 1:
The system performs preliminary actions by establishing bidirectional communication links and negotiating fueling parameters before the actual fueling process begins. The vehicle terminal and dispenser terminal exchange capability information and agree on communication protocols in advance, enabling faster and more efficient fueling operations without compromising ease of use.
Solution Approach 2:
The patent introduces dynamic parameter adjustment capabilities through bidirectional communication, allowing the system to adapt fueling rates, pressure parameters, and timing based on real-time conditions. This dynamic optimization significantly improves fueling efficiency while maintaining user-friendly operation through automated control.
3Reliability
If unidirectional communication is used in hydrogen fueling, then the protocol implementation is simple, but the safety monitoring capability is insufficient
Solution Approach 1:
The bidirectional communication system enables comprehensive safety monitoring through continuous feedback loops. The dispenser terminal can send safety status information, temperature readings, and pressure data to the vehicle terminal, while the vehicle terminal can send safety commands and receive alerts, creating multiple layers of safety verification that unidirectional communication cannot provide.
Solution Approach 2:
The communication protocol acts as an intermediary that mediates safety information exchange between the vehicle and dispenser systems. It translates and standardizes safety-related data formats, enabling different systems to understand and respond to safety conditions appropriately without requiring complex direct integration.
4Adaptability or versatility
If conventional fueling control methods are used, then the system is compatible with existing infrastructure, but the scalability for large-scale fueling is limited
Solution Approach 1:
The patent implements a universal bidirectional communication framework that can serve multiple functions: fueling control, safety monitoring, status reporting, and diagnostic capabilities. This multi-functional protocol enables the system to scale from individual fueling operations to large-scale networks while maintaining consistent control mechanisms and interoperability across different terminals and vehicles.

AI summary
A method according to an exemplary embodiment of the present disclosure comprises steps in which a mobility: on the basis of a fueling protocol determined by means of a negotiation between a dispenser and the mobility, transmits, to the dispenser, a request message including information related to an operation including starting or suspension of hydrogen fueling; and receives, from the dispenser, a response message including information about whether the mobility has processed or is prepared to process the operation included in the request message.
